UPDATE: George Zimmerman won't quit trying to profit off of injustice. The gun Zimmerman used to fatally shot Trayvon Martin is back up for sale on United Gun Group. The company said of the listing, "as long as Mr. Zimmerman (or any other UGG member) is obeying the letter of the law, his personal firearm sale will be permitted on our network."

Zimmerman posted a listing on the auction site, Gun Broker, marketing the weapon as a "piece of American History." The bidding was set to begin Thursday at a whopping $5,000, but was shut down before it started.

According to BBC News, Congressman Hakeem Jeffries said that, "Trayvon Martin's cold-blooded killer should be in prison. Instead, he is trying to profit from the stunning miscarriage of justice."

Disgustingly, this isn't the first time Zimmerman has tried to profit from the notoriety he gained from killing an innocent teenager and getting away with it.

Zimmerman's attempts to capitalize on this "15 minutes of fame" clearly shows he doesn't understand how detested he is by the public.

In addition to his infamous 9 mm handgun being removed from the auction site, Smithsonian officials released a statement denying Zimmerman's claims that they had expressed interest in purchasing the firearm.

"The Smithsonian has never expressed interest in collecting George Zimmerman’s firearm," the statement read. "The Smithsonian has no plans to ever collect or display this object in any of its museums."

Just when you think George Zimmerman couldn’t stoop any lower, he manages to defy our already very, very low expectations.

The unrepentant Zimmerman announced his decision Wednesday night in an interview with Florida’s WOGX and explained he recently received his weapon back from the Justice Department. He said it’s time to “move past the firearm,” which would otherwise be “put in a safe for [his] grandkids.”

He also stated he had had death threats during his time in hiding and several more after he announced his decision to sell the gun.

"What I've decided to do is not cower," he said. "I'm a free American. I can do what I want with my possessions.”

That obviously includes making a lot of moolah from a weapon that took an innocent life as the bid for the gun is going to start at a whopping $5,000.

He is also extremely proud of his killing machine and calls it an “important piece of history” and claims the Smithsonian expressed an interest in acquiring it.

Zimmerman is also proud to announce that a portion of the proceeds will be used to “fight BLM violence against law enforcement officers, ensure the demise of Angela Corey’s persecution career and Hillary Clinton’s anti-firearm rhetoric.”

“Now is your opportunity to own a piece of American history,” Zimmerman wrote on the auction website.
